Hi, my name is

Maina Wycliffe

I am a Typescript enthusiast who loves exploring and teaching developers the ins and outs of Typescript and it's typing system. When developers develop an innate understanding of Typescript, they become more productive instead of spending more time fighting with Typescript. This is why I started my free newsletter All Things Typescript.

I am also a Full-stack Software Engineer, Google Developer Expert and Mentor.
